Hydrogen loss and its improved retention in hydrogen plasma treated a-SiN :H films: ERDA study with 100 MeV Ag7+ ions

Two-Center Effect on Low-Energy Electron Emission in Collisions of 1-MeV/u Bare Ions with Atomic Hydrogen, Molecular Hydrogen, and Helium. I. Atomic Hydrogen

Thermal Plasma Source of Hydrogen Atoms and Ions

A cascade arc is used as a source for a hydrogen/argon particle beam. The plasma is produced at thermal plasma conditions in the pressure range of 0.1 to 1 bar. It is expanded with a high velocity into a vacuum chamber. Measurements with a Langmuir double probe and with a mass spectrometer are performed. The resulting parameters of the plasma and the extracted ions are discussed. Molecular proc...

The Transport of Neutral Hydrogen Atoms in a Hydrogen Plasma

An analytical version of the discrete ordinates method is used to solve a class of boundaryvalue problems based on a linear Boltzmann equation relevant to the transport of neutral hydrogen atoms in a hydrogen plasma. In addition to a complete development of the discrete ordinates method for the considered application, the computational algorithm is implemented to yield very accurate results for...

H- production in pure hydrogen discharges of surface-plasma sources

2014 The pure-hydrogen discharges in surface-plasma sources with a semiplanotron electrode configuration are described. In short pulse (10-3 s) mode the extracted Hemission density was up to 1.1 A/cm2 at cathode discharge current density 60 A/cm2. The multi-slit short pulse extraction delivered the Houtput with current of up to 1 A. In the long pulse (0.6 s) mode the Hyield was 0.15 A at discha...
